Which element is reduced in the reaction below? Fe²⁺ + H⁺ + Cr₂O₇^2- → Fe³⁺ + Cr³⁺ + H₂O A)Cr B)Fe C)H D)O

Question

Quizplus · Accepted Answer

In the reaction, Fe is oxidized from a +2 oxidation state to +3 oxidation state, while Cr is reduced from +6 oxidation state to +3 oxidation state. The reduction of Cr indicates that it gains electrons and thus is the element being reduced. Therefore, the best choice is A) Cr.
